.genmodel reload forces encoding of OCL expressions in annotations. [message #540456]

Hi,

I update my model source, .xsd in this case.
In the schema, I add annotations which contain OCL expressions. (For
derived features). I then reload my .genmodel with the latest schema.
This is all fine, and I can generate the features.

I however later find out, my OCL expressions fail because the "greater
than" character has been encoded when reloading my schema.

So an expression like 'self->closure(...)' becomes 'self-&;closure(...)'

I presume the serializer encodes the element content in appinfo?

<xs:appinfo source="http://www.eclipse.org/OCL"
ecore:key="derive">self->closure(elements)
</xs:appinfo>

Any solution for this?
thx Christophe

Christophe,

It looks like a double encoding problem. Please open a bugzilla.

Hi Christophe, Ed

Interesting: I had no idea OCL had spread into XSD.

Is there any documentation/examples that I can refer to myself and
reference from MDT/OCL documentation.

I'm a bit puzzled by the http://www.eclipse.org/OCL URI which seems
inconsistent with the new delegates URI.

Ed,

What Christophe's referring to is generalized support for mapping XSD
annotations to Ecore annotations. It works this same way regardless of
the actual values involved.
